IMPROVEMENT IN ROTARY CHURN-DASHERS.

Specification forming part of Letters Patent No. 164,215, dated June 8,1875; application filed April 10, 1875.

To all whom it may concern:

Be it known that I, JAMES J. ROBINSON, of Gibson City, in the county ofFord and State of Illinois, have invented a new and useful Improvementin Ohurn-Dasher, of which the following is a specification:

Figure 1 is a side view of my improved churn-dasher. Fig. 2 is a topView of the same.

Similar letters of reference indicate correspondin g parts.

The object of this invention is to improve the construction of thechurn-dasher for which Letters Patent No. 51,354 were issued to meDecember 5, 1865, so as to make it simpler in construction, cheaper inmanufacture, more effective in operation, more easily operated, andcause it to gather the butter quicker and more thoroughly.

The invention consists in a churn-dasher in which bars provided at theirends with crossbars and disks are attachedto the shaft in an inclinedposition, and are so arranged that the upper cross-bar and disks of eachlower bar may be upon a level with the lower cross-bar and disks 'of thenext upper bar; and in the combination of the adjustable gathering-boardwith the dasher-shaft, provided with the bars, the cross-bars, and thedisks, as hereinafter fully described.

A is the dasher-shaft, upon the lower end of which is a pivot, to workin a step or socket in the center of the bottom of the churn, and whichis designed to be driven by gear-wheels, in the manner of ordinaryrotary dashers. Through the lower part of the shaft A are formed anumber of inclined holes, at different distances from the lower end ofsaid shaft A, through which are passed a number of bars, B. To the endsof the bars B are attached, short cross-bars 0, having disks D formedupon or attached to their ends. The bars B are so arranged that theupper cross-bar and disks 0 D of each lower bar B may be at the samelevel as the lower cross-bar and disks 0 D of the next upper bar B.

By this construction a less number of the bars, cross-bars, and disks BO D will be required to produce the same effect than when the bars B arehorizontal, as in Letters Patent No. 51,35I. This construction makes thecost of manufacture less, and also lessens the labor of operating thedasher.

In the upper part of the shaft A is formed a number of holes, a, atdifferent heights, to receive the shank of the board E, so that theboard E may be moved up or down, to adjust it according to the amount ofmilk in the churn.

The board E, as the shaft A is slowly revolved, quickly gathers thebutter into a compact mass.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The combination of shaft A, oblique bars B, cross-barO, and disks D, constructed and arranged substantially as and for thepurpose specified.

JAMES J. ROBINSON.
